Álvaro Serrano thoroughly examines the current landscape of photography gear:

“But first, let’s take the obvious out of the way: there are no bad cameras or lenses out there anymore. That’s a fact. It is extremely likely that whatever camera you already own is perfectly capable of taking really great pictures, if you take the time to learn how to use it. So be advised: a “better” camera will not magically make you a better photographer. If you’re happy with what you already own, just keep it, stop reading now and go take some awesome pictures. This is all just splitting hairs, really.”
